FLUSHlNG-TANK VALVE.

Specification of Letters Patent.

Patented March 5, 1907.

Application filed May 31, 1906. Serial No. 319,534.

To all whom it may concern:

Be it known that I, WILLIAM H. Lrinnwre, of Rock Island, in the countyof Rock Island new and useful Improvements in Flushing- Tank Valves; andI hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,which form part of this specification.

This invention is an improved ball-valve for flush-tanks of closets; andits object is to obtain a sudden closing of the supply-valve, also aquick opening thereof, also an automatic quick closing of theflush-valve simultaneously'with the opening of the supplyvalve, and tocontrol all these operations by one float; also, to provide means forregulating the closing of the valve quickly at any desired water-level,to prevent hammering in the water-pipes when the valve is closed, and toutilize the flushing-valve stem as an over flow.

My novel valve construction is equally well adapted for use in broadshallow tanks located overhead or in deep narrow tanks located justabove the bowl, as I dispense with the necessity for a siphon connectionin the flushing-tank.

Subordinate features of the invention are the accessibility of parts,the easy adjustment thereof, and the capability of removal of the partsfrom the tank without taking it down.

A practical form of the invention is illustrated in the accompanyingdrawings ,-which I will describe in detail and refer to the claimsappended to the specification for summaries of the features andcombinations of parts for which protection is desired.

In said drawings, Figure 1 is a side elevation of the complete apparatuswithin a tank, the side of the tank being broken away to show theconstruction and the parts being shown in position with float raised andthe water-inlet valve and the flushing-valve closed. Fig. 2 is asectional view showing the inlet-valve in open position. Fig. 3 is afull-size plan view of the inlet-valve mechanism. Fig. 4 is aperspective view of the part shown in Fig. 2, showing the valve in openposition. Fig. 5 is a perspective view of the upper part of theinlet-valve casing. Fig. 6 is a perspective view of the valve andvalvelever detached. Fig. 7 is a perspective view I of the float-levercasting detached with the l adjustable tripping device. Fig. 8 is adetail view of a slight modification.

The tank is of any preferred form and construction. To the bottomthereof is attached the inlet-valve casing comprising a lower portion 1and an upper part 2, which are separable horizontally and united byscrews 1. The lower part 1 is provided with a nipple 1 to which thewater-supply pipe W is attached. It is also provided with a lateralbranch 1, to which is connected an airchamber 1 which may be formed by aclosed cylinder or piece of piping, as shown. The object of this chamberis to prevent pounding in the pipes when the water is suddenly stoppedby the closing of the valve. The upper part 2 of the valve-casing isprovded with a depending annular flange 2 entering part 1 and formingthe valve-seat. It also has an upstanding cylindric flange 2 which ispreferably cut away on one side to admit more ready escape of watertoward the center of the tank.

The inlet-valve 3 is preferably a ball or bullet valve adapted to seatagainst flange 2 and secured on a stem 3, which extends upward throughthe opening in part 2 and has a depending flared skirt-flange 3 on it,above and overreaching the flange 2 and adapted to check the upward flowof water through the valve and direct it downwardly and outwardly aroundthe valve-casing into the tank. A coiled expansion-spring 3 ispreferably interposed between the skirt-flange and part 2 of the casingfor the purpose of both preventing rattling of the valve-stem when thevalve is open and also to assist in quickly closing the valve when thelatter is permitted to close. As shown in Figs. 1 and 2, the valvecloses with the current, and consequently the spring does not have to bevery strong, and, in fact, does not necessarily have to be used; but itgives a quicker closing action to the valve and renders it more quietwhen open.

The valve-stem is provided at top with ears 3*, by which it is pivotallyconnected by a pin 3 to one end of a rocking lever 4, which is pivotedon a pin 4 transfixing arms 2 rising from a lateral extension of part 2of the casing adjacent the valve-stem. The rear end of lever 4-isadapted to be engaged by a flat spring-catch 4 fastened at its lower endby screws 4 to an extension 2 of part 2, and when the valve is fullyopen the upper end of spring 4 engages under the outer end against thewater. The other portions of the device remain practically the same inconstruction and effect, the spring 3 performing the function of spring3 in closing the valve, but closing it downwardly instead of upwardly.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. The combination of an inlet-valve, a lever to which the valve ispivotally connected. a catch for locking said valve open, a float, afloat-lever adapted to open the valve when the float descends, and atrip operated by said float-lever for disengaging the catch when thefloat rises to the proper waterlevel.

2. The combination of a valve-casing, a valve therein, means for closingthe valve, a rocking lever to which the valve-stem is pivotallyconnected, a catch for locking said lever to hold the valve open, afloat, a floatlever adapted to open the valve when it descends, andmeans operated by said floatlever for disengaging the catch when thefloat rises to the proper water-level.

3. In combination, an inletvalve, an oscillating lever pivotallyconnected to the valve-stem, a spring-catch engaging the lever to holdthe valve in open position, a second lever, a float connected therewith,means whereby the float-lever causes the opening of the valve when thefloat descends, and a tripping-finger on said float-lever adapted todisengage the catch from the first lever and permit the valve to closewhen the float rises to the proper point.

4. The combination of a valve-casing, an oscillating lever pivoted onsaid casing, an inlet-valve having its stem pivotally connected to saidlever, a catch adapted to lock the valve in open position, a secondlever pivoted beside the first lever, a float connected with said secondlever, the second lever being adapted to engage the first lever and openthe valve when the float descends, and a tripping device on the secondlever adapted to release the valve-catch when the float rises.

5. The combination of a valve-casing, an oscillating lever pivoted onsaid casing, an inlet-valve having its stem pivotally connected to saidlever, a spring-catch adapted to lock the lever when the valve is open,a second lever pivoted beside the first lever, a float connected withsaid second lever, an adjusting device on the second lever adapted toengage the first lever, and open the valve when the float descends, andan adjustable tripping device on the second lever adapted to disengagethe catch from the first lever when the float rises.

6. The combination of a valve-casing, a lever pivoted on the upper partof said casing, a valve-stem pivotally connected to one end of saidlever, a valve on said stern, a spring for closing said valve, afloat-lever pivoted beside the first lever, a float adapted to cause thefloat-lever to actuate the first lever when the float descends, aspringcatch for locking the valve-lever when the valve is opened, andmeans for disengaging the catch from the valve-lever when the floatrises.

7. The combination of a two-part valvecasing, a lever pivoted on theupper part of said casing, a valve-stem pivotally connected to one endof said lever, a valve on said stem, a spring for closing said valve, afloatlever pivoted beside the first lever, a float adapted to cause thefloat-lever to actuate the first lever when the float descends, aspring-catch for locking the valve-lever in opened position, and atripping device adjustably attached to said float-lever adapted todisengage the catch from the valvelever when the float rises.

8. In a tank inlet-valve, the combination of a casing having avalve-seat, a valve-stem, a dispersing skirt-flange on said stem abovethe seat, and a valve on said stem; with an oscillating lever from whichthe valve-stem is suspended, a spring-catch for lockingsaid lever whenthe valve is open, an oscillating float-lever pivoted beside the firstlever adapted to engage the latter when the float descends and open thevalve, and a tripping device adapted to disengage said catch from thelever when the float rises to the desired point.

9. In a tank inlet-valve, the combination of a valve-casing having avalve-seat, a valve-stem passing through said seat, a dispersing-flangeon said stem above the seat, a valve on said stem below said flange, anda spring for closing the valve; with an oscillating lever from which thevalve-stem is suspended, a spring-catch for locking said lever when thevalve is open, an oscillating floatlever pivoted beside the first lever,a device on said lever adapted to engage the first lever when the floatdescends and open the valve, and an adjustable tripping device on thefloat-lever adapted to disengage said catch from the first lever whenthe float rises to the desired point.

In testimony that I claim the foregoing as my own I aflix my signaturein presence of two witnesses.
